Most flowering plants, such as roses, have heavier, waxy pollens that do not trigger allergies.

When is pollen season?

Each type of plant has a pollen season. Some things bloom in the spring, others bloom in the fall. Pollen season usually starts in the spring, but may begin as early as January in the western areas of the U.S. The season usually lasts until November.

Can allergic rhinitis in pollen season be prevented?

To lessen the effects of allergic rhinitis during pollen season, the American Academy of Allergy, Asthma, and Immunology suggests the following:

Keep windows closed at night and use air conditioning, which cleans, cools, and dries the air.

Minimize outdoor activities early in the morning, between 5 a.m. and 10 a.m., when pollen is most prevalent.

Keep car windows closed when traveling.

Take vacations in areas where pollen is not as prevalent, such as the ocean.

Give your child his or her medications, as prescribed by his or her health care provider.

Minimize your child's time spent outdoors when the pollen count is high.

Do not rake leaves or have your child jump in piles of raked leaves during pollen season.
